here's user StarScream's tub set-up for his lil' Mazikeen, cluttered-up and beautiful:
here's user MissterDog's divided T8 setup, honestly one of my favorites! she made a lot of the "rock" decor herself!!!
a craft store would be a good place to look for fake foliage and stuff. make sure to clean and disinfect it before anything goes into his home.
my T8 (4' x 2' x 1') only has a couple of those fake leaf strands in it and it does a pretty good job of cluttering up the joint. i wish i had a picture but i don't!
EDIT: paper towel/toilet paper tubes make EXCELLENT cheap hides for baby snakes once you stuff one end with paper towel or something of the like! you could definitely use one or two of those for the meantime.
